PHOTOGRAPHIC DEVELOPING-PAPER HOLDER.

SPEGIFIGATIO'N forming part of Letters Patent No. 689,300, datedDecember 1'7, 1901. Application filed November 12, 1900. Serial No. 36,185. (No model.)

T all whom it may concern: e

Be it known that I, EMERSON A. GILBERT, a citizen of the UnitedStates,residin g at Jamestown, in the county of Chautauqua and State ofNew York, have invented a new and useful Photographic Developing-PaperHolder, of which the following is a specification.

The quick-developing papers now in use for printing-out purposes andwhich for many reasons are greatly preferred by photographers demandsuch strong and poisonous developing solutions that many operators aredeterred from using them, the solutions eating the fingers and producinggreat cracks, which are almost non-healing.

The object of my invention is to provide a simple and convenient holdeiIor dipper for the damp paper, whereby the hands of the operator need notenter the developing solution and upon which the damp paper may lieflat, the low sides of the flat bottom of the dipper allowing the easydippingin the solution, yet preventing the paper from floating off theholder. It is essential that the developing-surface of the paper shallnot be touched bya clasp, a finger, or any object while in thedeveloping solution or while the paperis damp therewith, or finger-marksand stains will be the result. My holder allows the paper to developclean to the edge, and a finger-hole allows of the easy removal of thepaper from the holder without touching the developed or upv per surface.I attain this object by my device as shown in the accompanyingdrawings,in which- Figure 1 is a perspective view of iny holder with the paper inposition for developing. Fig. 2 is a plan view of my holder with solidflat bottom, as I usually make it. Fig. 3 is a plan view of holder withperforated bottom. V

10 is the handle of the holder, Which may be made in any strong andsuitable manner which shall keep the fingers out of the solution.

11 is the flat bottom of the holder, which I make solid for mostpurposes, since perforations like 12 or a sieve bottom sometimes formbubbles in the solution and do not do even work.

13 is the side of the flat bottom, which is made low, from a sixteenthto an eighth of an inch serving my purpose, which is to hold the damppaper on. the flat bot-tom and allow it to be easily and quickly dippedin the solution and to hold a thin even body of the solution on thepaper, which is then drained off and the holder is dipped in the bath.

I prefer to make finger-hole 15 in the end of the flat bottom oppositethe handle, since my holder can then be used with equal ease by a rightor left handed operator, and fingerhole 15 should be made sufficientlylarge for' the finger-tip to be. inserted under the paper to lift thesame from the under side, for in using my holder the wet paper is spreadon the flat bottom with the developing side up. It is then dipped with asteady hand in the developing solution, allowing the developer to flowevenly over the surface of the paper. After draining it is dipped in thebath and quickly raised by the finger-tip from `the under side, the Wetpaper sticking to the finger and the finger not touching the uppersurface v of the paper, thus preventing all stains or the rucking of thepaper in taking it from the holder.

I make my holder of aluminium, hard rub- .low sides might be cut atdifferent points to aid in draining the paper; but I find that thesolution easily drains over the low, sides 13 and through thefinger-hole 15 and the closed sides better hold an even body of thesolution on the paper.

Some operators prefer to pour the solution over the paper instead ofdipping the paper in the solution. This is more easily accomplished withmy holder than in a large tray, since it is only necessary to pour thesolution evenly over the paper on the flat bottom and then spread itwith a gentle motion of the holder, after Which drain off.

I claim as new-- IOO
